i've got 74 vette with a new longblock on the 350 and a muncie m20 transmission and the thing aint real good at off the line accel so i was thinking of puttin 3.73 or maybe 4.10 gears in the rearend to help. Would i have to buy a whole new rearend and would this help my accel problem?

In your vette I think 3.73 should be plenty of gear.But I would first check your distributor advance curve and carb,you probably only need some adjustment.The four speed would make up any short falls your motor might have.

I don't know what gears you have now, but I can vouch for the fact that an M-20 with 3.08's is a PITA to get moving without slipping the stink out of the clutch, especially considering the soggy bottom end typical of the early-'70s smog motors.

I changed my '72 Nova from a Saginaw with a low gear similar to an M-20 to a Sag with a 3.11 low gear, a change that would mimic a change from 3.08 to 3.73 gears, and I like it MUCH better.

took your advice started a new thread thanks, i was always told in a 4 speed drag car unless you can afford a dual disc-er to do one of 2 things. one, run a bad *** pressure plate with a stock disc or a bad *** disc with a stock pressure plate its suppose to allow enough slippage without grenading anything to badly. must work couple of guys here leave at 7200 on the slicks and have had good seasons. i currently have mickey sportsmans they dont hook very good anyway at least with a stick u can somewhat control your spin at the launch.
